Hi Maz,
I have the T200 and am mobile.
I work every evening (bar sat + sun) and find that the gun does not have to be cleaned after each client. My gun is fine for 8 clients per evening.
I clean my gun each day b4 going to work, which works for me, but my supplier states that this should only need doing once a week. I wouldnt risk that personally as I wouldnt want anything to effect the outcome of any tan.
So, what works for me is cleaning the gun once a day b4 work and the filter once a week.
Here is how I clean the gun.
1. Strip the gun down completely and soak all components in hot soapy water for 5mins.
2. Rinse and dry all components.
3. Spray all parts with WD40.
4. Rebuild the gun.
5. Fill cup with hot water and spray until cup is empty.
Hope that Helps
